DRAW-BAR FOR RAILROAD-CARS.

SPECIFICATION forming part of Letters Patent No. 560,436, dated May 19,1896.

Application filed August 10, 1895. Serial No. 558,897. (Nomodel.)

To all whom t may concern:

Be it known that I, JOHN SHAW, of Woodburn, in the county of Marion andState of Oregon, have invented certain new and useful Improvements inRailroad-Cars, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide certain new and usefulimprovements in railroad-cars, whereby the cars in a train are relievedof all pulling and pushing, strain, jerks, and jams, thereby freeing thecar-body of the weight of the train.

The invention consists principally of a frame extending longitudinallyon the under side of the car from one end to the other, the said framebeing mounted to slide, and springs interposed between the frame and thebody of the car to take up .the strain.

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the gures.

Figure l is a sectional side elevation of the improvement. Fig. 2 is aninverted plan view of the same with parts in section, and Fig. 3 is anenlarged cross-section of the same on the line 3 3 of Fig. l.

The car is provided on the under side of its body with alongitudinally-extending frame formed at its ends with draw-heads A andA', containing the draw-bars B, rigidly connected with each other bysets of upper and lower tubes or pipes C and O', between which extendloosely some of the transverse beams D and D of the body of the car E.The several tubes are connected with each other by ties O2 for thepurpose of making the frame as stiff as possible. The frame thus formedis provided between the beams D D with casings F, into each of whichextends a rod G, pivotally connected with a keeper H, held on theadjacent car-beam D. On the rod G within the casing F is Y coiled aspring I, resting with one end on a washer J, attached to the rod Gr andwith the other end attached to a washer J', adapted to abut against lugsF', secured to the inside of the casing. Now it will be seen that when apull or push is exerted on the frame in either direction the strain istaken up by the springs I in the casings F, and consequently thecar-body is relieved of all strain, jerks, jams, and the like incidentto the car while traveling on the road. In order to facilitate thesliding of the frame, I mount the same on rollers K, journaled inU-shaped hangers L, hooked onto staples L', attached to the under sideof the car-body, as plainly indicated in Figs. l and 3. The draw-bars Bare yieldingly mounted in the usual manner in the draw-heads A A' andare supported at their sides, top, and bottom by springs N, preferably.in the form of elliptical springs, as indicated in Fig. 2. Thesesprings N serve to hold the draw-bar in the center of the draw-head andalso permit the draw-bar to swing to either side when the car passesaround curves, or to swing up and down when entering upon or leaving agrade, or when the cars to be coupled are not of the same height.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. A railroad-car, provided with a frame mountedto slide longitudinally on the under side of the car, and formed at itsends with draw-heads containing the draw-bars, casings held on the saidframe, rods connected with a xed portion of the car, and springs coiledon the said rods within the said casings, substantially as shown anddescribed.

2. A railroad-car, provided With a frame mounted to slide longitudinallyon the under side of the car, and formed at its ends with draw-headscontaining the draw-bars, casings held on the said frame, rods connectedwith a fixed portion of the car, springs coiled on the said rods Withinthe said casings, and Washers held on the said rods, to engage the endsof the springs, substantially as shown and described.

3. A railroad-car provided with a drawframe having casings, eachprovided with lugs, washers held in the said casing and one resting onthe said lugs, a rod engaging the said washers and connected with thecar-body and a spring on the said rod between the said Washers,substantially as lshown and described.

ICO

the frame and rigid with the car, and a cushioned connection between thebeam and frame, substantially as described.

G. The combination with a ear, of a frame longitudinally movable beneaththe car, a cushioned connection between the frame and car, a draw-headat each end of the frame, and U-shaped hangers pivotally mounted on thecar and embracing the frame, substantially as described.
